Ishii Yuuko(石井優子)

Ishii Yuuko is a JAV actress who debuted around the mid-2000s and has maintained a career spanning roughly a decade. While the available information provides only a partial list of her works, it suggests a focus on mature themes and larger-breasted women throughout her career. Her early works, such as those released by Ruby, showcase a concentration on "kyonyuu" (large breasts) and "jinzuma/shufu" (married women/housewives) themes, often featuring lingerie and group sex scenarios. Later works still emphasize the "kyonyuu" fetish but also explore the athleticism of the performers, as seen in releases from ROOKIE and Moodies. This suggests a possible broadening of her genre appearances over time. Ishii Yuuko has worked with several studios, including Ruby, Moodies, and ROOKIE. She is known for her appearances in the "Kyonyuu Tsuma" series by Ruby. Her work often highlights her physical attributes, particularly her large breasts, within the context of mature-themed scenarios and, later, athletic-themed performances.
